I don't have one. It's to tinker with my first esp32 board and lora.
It's basically a hobby. If you live somewhere super rural or something it might be interesting to chat with your neighbor or whatever but I think meshtastic is still too much in the alpha stage to be usable really.
It might be useful on a festival or something, where cell networks are overloaded and you and your friends can contact each other via meshtastic. Idk if that would work though.
If you want to use multiple internet connections and combine their speed, that's possible. Dunno how though and I guess to work best it would need a server somewhere else like a VPN to manage the packets coming from different ips
Because it's not useful. Two routers still share the same frequencies and thus can't send more data over the same air. A single router can already use multiple frequencies to increase throughput. You don't need two to do that.

yup.
But I have to post it with the original title, correct? Or would it be fine for me to give it a more descriptive one?
